India's latest shift in the economics of Unified Payments Interface, or UPI, may do more than alter merchant payment costs. It could redraw the competitive map of the country's digital payments market by strengthening the two incumbents already most deeply embedded in consumer behavior: PhonePe and Google Pay.
According to Bernstein estimates, the new merchant fee regime could allow the two platforms to earn roughly $900 million annually by March 2028. The policy introduces a 0.4% fee on merchant transactions above Rs 2,000, creating a fresh revenue pool in a system that has long been defined by free, instant transfers and razor-thin monetization. For the largest players, the change is not merely a new income stream; it is a structural tailwind that could widen the gap between scale leaders and the rest of the market.
Scale Advantage Deepens
The significance of the fee shift lies in how UPI has evolved. What began as a public digital payments utility has become the default transaction layer for millions of Indians, especially in urban retail, transport, and e-commerce. Yet the ecosystem's growth has not translated evenly into profits. Most payment apps have spent years subsidizing user acquisition, merchant onboarding, and incentives in a market where transaction volumes are enormous but monetization has been limited.
That dynamic now appears to be changing in a way that favors the biggest platforms. PhonePe and Google Pay already command the largest share of UPI transactions and have the broadest merchant acceptance networks. A fee on higher-value merchant payments gives them a better path to monetization because they are best positioned to capture the largest share of transaction flow. In effect, the policy rewards distribution, brand trust, and merchant density — all areas where incumbents hold a clear lead.
The Bernstein projection of $900 million in annual revenue by March 2028 underscores how meaningful even a modest fee can become at UPI's scale. For smaller competitors, the same regime may be far less forgiving. If they cannot match the reach of the leaders, they may be pushed toward niche strategies, narrower merchant segments, or higher-value transactions where fee economics are more attractive.
Rural Push, New Battleground
The fee change could also alter where payment apps compete. Analysts expect it may encourage platforms to expand more aggressively into rural markets, where digital payments adoption is still rising and merchant relationships remain fragmented. For large apps, rural expansion offers a way to broaden transaction volume and deepen user engagement beyond saturated urban centers.
That matters because the next phase of UPI growth is likely to be less about first-time adoption and more about transaction quality. If higher-value merchant payments become more lucrative, payment companies will have an incentive to cultivate merchants and consumers who transact larger amounts more frequently. This could accelerate efforts to onboard small businesses, local retailers, and service providers in tier-two, tier-three, and rural markets.
For smaller rivals, however, the economics may become harsher. They may struggle to compete on incentives against better-capitalized incumbents while also facing pressure to prove a viable route to revenue. The result could be a market that becomes more concentrated, not less, even as overall UPI usage continues to expand.
Policy With Market Effects
The broader policy implication is that a fee regime designed to monetize digital payments may also entrench the platforms already best placed to benefit from it. That is a familiar pattern in digital markets: once a network reaches a certain scale, new revenue rules can amplify the advantage of the largest players rather than level the field.
For India, the challenge will be balancing sustainability with competition. UPI has been one of the country's most successful digital public infrastructure stories, but its long-term economics have remained under strain. Introducing merchant fees above a threshold may help create a more durable commercial model. At the same time, it risks making the market less contestable if smaller apps cannot keep pace.
The immediate winners appear clear. PhonePe and Google Pay, already dominant in consumer payments, stand to gain both from direct fee income and from the strategic leverage that comes with it. The larger question is whether the new regime will foster a healthier payments ecosystem — or simply make the leaders bigger still.
